Cannabis-Induced Anxiety Disorder in the Emergency Department.

BACKGROUND: In December 2018, Michigan became the 10th state to legalize marijuana for adults. Since this law took effect, increased availability and use of cannabis in Michigan have led to increased emergency department (ED) visits associated with the drug's psychiatric effects. OBJECTIVES: To describe cannabis-induced anxiety disorder's prevalence, clinical features, and disposition in a community-based study. METHODS: This was a retrospective cohort analysis of consecutive patients diagnosed with acute toxicity related to cannabis use (ICD-10 code F12). Patients were seen at seven EDs over a 24-month study period. Data collected included demographics, clinical features, and treatment outcomes in ED patients who met the criteria for cannabis-induced anxiety disorder. This group was compared to a cohort experiencing other forms of acute cannabis toxicity. Chi-squared and t-tests were used to compare these two groups across key demographic and outcome variables. RESULTS: During the study period, 1135 patients were evaluated for acute cannabis toxicity. A total of 196 patients (17.3%) had a chief complaint of anxiety, and 939 (82.7%) experienced other forms of acute cannabis toxicity, predominantly symptoms of intoxication or cannabis hyperemesis syndrome. Patients with anxiety symptoms had panic attacks (11.7%), aggression or manic behavior (9.2%), and hallucinations (6.1%). Compared to patients presenting with other forms of cannabis toxicity, those with anxiety were likelier to be younger, ingested edible cannabis, had psychiatric comorbidities, or had a history of polysubstance abuse. CONCLUSIONS: Cannabis-induced anxiety occurred in 17.3% of ED patients in this community-based study. Clinicians must be adept in recognizing, evaluating, managing, and counseling these patients following cannabis exposure.

High-efficiency Practices of Residents in an Academic Emergency Department: A Mixed-methods Study.

BACKGROUND: Emergency department utilization and crowding is increasing, putting additional pressure on emergency medicine (EM) residency programs to train efficient residents who can meet these demands. Specific practices associated with resident efficiency have yet to be identified. The objective of this study was to identify practices associated with enhanced efficiency in EM residents. METHODS: A mixed-methods study design was utilized to identify behaviors associated with resident efficiency. In Stage 1, eight EM faculty provided 61 efficiency behaviors during semistructured interviews, which were prioritized into eight behaviors by independent ranking. A total of 31 behaviors were tested, including additions from previous literature and the study team. In Stage 2, two 4-hour observations during separate shifts of 27 EM residents were performed to record minute-by-minute timing and frequency of each behavior. In Stage 3, the association between resident efficiency and each of the behaviors was estimated using multivariable regression models adjusted for training year and clustered on resident. The primary efficiency outcome was 6-month average relative value units/hour. A sensitivity analysis was performed using patients/hour. RESULTS: Seven practices were positively associated with efficiency: average patient load, taking initial patient history with nurse present (number/hour, number/new patient), running the board (number/hour), conversations with other care team members (number/hour, % time), dictation use (number/hour, % time), smartphone text communication (number/hour, % time), and nonwork tasks (number/hour). Three practices were negatively associated with efficiency: visits to patient room (number/patient), conversations with attending physicians (% time), and reviewing electronic medical record (number/hour). CONCLUSION: Several discrete behaviors were found to be associated with enhanced resident efficiency. These results can be utilized by EM residency programs to improve resident education and inform evaluations by providing specific, evidence-based practices for residents to develop and improve upon throughout training.

End-tidal CO2 Monitoring is Available in Most Community Hospitals in a Rural State: A Health System Survey.

INTRODUCTION: Procedural sedation and analgesia (PSA) provides safe and effective relief for pain, anxiety and discomfort during procedures performed in the emergency department (ED). Our objective was to identify hospital-level factors associated with routine PSA capnography use in the ED. METHODS: This study was a cross-sectional telephone survey of ED nurse managers and designees in a Midwestern state. Respondents identified information about hospital infrastructure, physician staffing, family practice (FP) physicians only, board-certified emergency physicians (EPs) only (or both), and critical intervention capabilities. Additional characteristics including ED volume and hospital designation (i.e., rural-urban classification) were obtained from the Centers for Medicare and Medicaid Services and the state hospital association database, respectively. The primary outcome was reported use of PSA capnography. We conducted univariate analyses (relative risks, 95% confidence interval [CI]) to identify associations between hospital-level characteristics and PSA capnography use. RESULTS: We had an overall response rate of 98% (n=118 participating hospitals). The majority of EDs were in rural settings (78%), with a median of 5,057 visits per year (interquartile range 2,823-14,322). Nearly half of the EDs were staffed by FP physicians only, while 16% had board-certified EPs only. Nearly all hospitals (n=114, 97%), reported using continuous capnography for ventilated patients, and 74% reported use of capnography during PSA. Urban hospitals were more likely to use PSA capnography than critical access hospitals (relative risk 1.45; 95% CI, 1.22-1.73), and PSA capnography use increased with each ED volume quartile. Facilities with only EPs were 1.46 (95% CI, 1.15-1.87) times more likely to use PSA capnography than facilities with FP physicians only. CONCLUSION: Continuous capnography was available in nearly all EDs, independent of size, location or patient volume. The implementation of capnography during PSA was less penetrant. Smaller, rural departments were less likely than their larger, urban counterparts to implement these national guidelines. Rurality and hospital size may be potential institutional barriers to capnography implementation.

Central Venous Access Capability and Critical Care Telemedicine Decreases Inter-Hospital Transfer Among Severe Sepsis Patients: A Mixed Methods Design.

OBJECTIVES: Severe sepsis is a complex, resource intensive, and potentially lethal condition and rural patients have worse outcomes than urban patients. Early identification and treatment are important to improving outcomes. The objective of this study was to identify hospital-specific factors associated with inter-hospital transfer. DESIGN: Mixed method study integrating data from a telephone survey and retrospective cohort study of state administrative claims. SETTING AND SUBJECTS: Survey of Iowa emergency department administrators between May 2017 and June 2017 and cohort of adults seen in Iowa emergency departments for severe sepsis and septic shock between January 2005 and December 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Multivariable logistic regression was used to identify independent predictors of inter-hospital transfer. We included 114 institutions that provided data (response rate = 99%), and responses were linked to a total of 150,845 visits for severe sepsis/septic shock. In our adjusted model, having the capability to place central venous catheters or having a subscription to a tele-ICU service was independently associated with lower odds of inter-hospital transfer (adjusted odds ratio, 0.69; 95% CI, 0.54-0.86 and adjusted odds ratio, 0.69; 95% CI, 0.54-0.88, respectively). A facility's participation in a sepsis-specific quality improvement initiative was associated with 62% higher odds of transfer (adjusted odds ratio, 1.62; 95% CI, 1.10-2.39). CONCLUSIONS: The insertion of central venous catheters and access to a critical care physician during sepsis treatment are important capabilities in hospitals that transfer fewer sepsis patients. In the future, hospital-specific capabilities may be used to identify institutions as regional sepsis centers.
